Rules change, and the deciding facts on any specific parcel (setbacks, perc results, overlay districts, deed restrictions, road frontage) live at the county or town office, not in any database. Before you buy land or build, confirm the current rules directly with the local zoning and health offices - the sources on this page tell you exactly who to call.
The local rulesBartholomew County, IN
Zoning & raw-land occupancy
RestrictedBartholomew County has its own Zoning Ordinance and Subdivision Control Ordinance, administered jointly with the City of Columbus's Planning Department, covering unincorporated county land and Hartsville by contract. Raw land use is governed by zoning district, not left unregulated. source
Dwellings, tiny homes & RVs
Varies locallyTiny homes are defined and allowed as single-family dwellings; ADUs are a conditional use requiring case-by-case review; manufactured home communities need a minimum 5 acres in an RMH district. Standalone RV-as-residence rules were not confirmed, so check with the Planning Department. source
Building permits & codes
RestrictedThe Department of Technical Code Enforcement of Columbus/Bartholomew County issues building permits and requires a site plan, and a Health Department septic release where applicable. source
Septic & composting toilets
Generally allowedThe county Health Department's Environmental Health division administers septic permitting under the state's standard on-site sewage rule (410 IAC 6-8.3); this is the state baseline applied locally. source
Greywater reuse
Unclear - verifyNo county-specific greywater ordinance was found; the state baseline treats greywater as part of sewage requiring septic-system compliance. Confirm specifics with the county Health Department's Environmental Health division.
Rainwater harvesting
Unclear - verifyNo Bartholomew County ordinance on rainwater harvesting was found; the state baseline allows it with no known prohibition, though plumbing tie-ins would fall under building permitting. Not confirmed at the county level.
Private wells & water rights
Generally allowedWell construction is licensed at the state level (DNR/health), and the county Health Department performs well-water inspections, notably at property transfer. Much of the county is also served by rural water utilities, though connection is not mandated. source
Living disconnected from utilities
Generally allowedNo Bartholomew County ordinance requiring connection to public electric, water, or sewer was found, so living off the public grid is workable provided septic and well permits are in place. source
